I feel like if you made Azir's ult come out in a cone he'd be alot more balanced for pro play
Cuz he'd lose his nearly-lane-wide full team insec that's honestly a bit too reliable at snatching multiple targets despite the risk it puts him in.
I'm talking like, one spawn point directly behind him where the soldiers all appear and fan out as they move forward to form the straight wall.
Still has team sweep potential, just not as reliable and this way his opponents can somewhat control/predict the direction they'll be flung in if used as an insec.
